As a supplementary explanation to the above embodiments, some embodiments further include a motor 106 fixed on the bracket for driving the fan blade; the heating part is connected with the power cord of motor, and the heating part acquires the power from the motor.
The heating component is arranged on the fan blade and rotates along with the fan blade. The heating component can rotate along with the fan blade, so that the heating component can dynamically generate heat in the rotating area of the fan blade instead of being limited at a certain position. Meanwhile, when the fan blades rotate, the generated heat can be rapidly transmitted to other places in the space, and defrosting is conveniently and rapidly achieved. Meanwhile, the heating part obtains a power supply from the motor, and the power supply does not need to be additionally installed to supply power to the heating part.
In some alternative embodiments, the heating member is powered from the motor by the conductive ring. Specifically, the heating component is connected with the first conductive ring, the power line of the motor is connected with the second conductive ring, and the second conductive ring is connected with the first conductive ring through an internal ball bearing device, as shown in fig. 2, the ball bearing device 202 is a small smooth iron ball fixed in the groove of the conductive ring 201, and the ball bearing device enables the second conductive ring to supply power to the first conductive ring through the ball bearing device even under the condition of high-speed rotation, so as to meet the power supply requirement of the electric heating wire. The heater block obtains the power from the motor through the conducting ring, when guaranteeing that the heater block follows the fan blade and rotates, the motor can be for the heater block power supply. The conductive ring is a device for transmitting power or signals to the rotating body, and is a common technical means in the art, and will not be described herein too much.
As an optional embodiment of the utility model, the heater block is electric heating wire, and electric heating wire surface insulation handles. Illustratively, the heating element is an iron-chromium alloy electric heating wire and is treated with oxidized coal powder to achieve insulation. The electric heating wires are embedded in the fan blades, and are uniformly distributed on the fan blades as much as possible in order to ensure that the heat generated by the heating component can be uniformly dispersed in the space; meanwhile, the electric heating wires are arranged in the edge area of the fan blade as much as possible, so that the area for generating heat is large.
